Excellent addon! Manuel, can you add functionality viewing png's and jpg's? - FF for desktop has that buld-in in the pdf-viewer. I push that with 70 Dollars as donation. Contact me please as soon as that is realised: eg9-add-gmx.de

Thank you so much. It's a shame about the hoops Mozilla is requiring for extensions, but this one is worth it!

Great addon!

It was good but no longer works ".Please use an ES-5 compatible build instead" I do not want to use an ES-5 compatible build instead . It must have updated in background .I have on android phone. i do not want to update.OK i got an old version 1.5.3 .since no way to stop update no reply i am getting rid of it

thats why i got rid. i decided what goes on my phone. when developers pay for the phonethey can decide

Very usefull. But after firefox android version 68 everything with addons was fucked. I rolled back to 68 in order to use pdf.js and other addons. Now i have a problem with the last version of pdf.js. if i use the older version it works, but after a while it auto updates, which is annoing. "Please use an ES-5 compatible build instead"

Best pdf viewer for Android.

An extension that should come preinstalled in Firefox for Android. As somebody else already said, it saves from deleting all the datasheets/scientific papers/whatever in the download folder that only had to be read once. Works perfectly as the desktop counterpart.

Fantástico Add-On, ahora se puede instalar para casi cualquier usuario en Nightly.

A great add-on!

This should be the no 1 pdf add on for firefox android. Simply excellent. Improves browsing experience immeasurably for anyone who frequently views pdfs.

こういうアドオンが欲しかった。
有り難い。
Android版FirefoxでもPDF.jsが使える😂

I love this app. So if this ability was available in the desktop version, why would Mozilla remove it in the mobile version? That just seems idiotic.

No need to clean my phone from hundreds of datasheets and articles every week anymore. Feels like a miracle.
